Lenaïg G Hemery, Kristin K Politano, Sarah K Henkel
With increasing cascading effects of climate change on the marine environment, as well as pollution and anthropogenic utilization of the seafloor, there is increasing interest in tracking changes to benthic communities. Macrofaunal surveys are traditionally conducted as part of pre-incident environmental assessment studies and post-incident monitoring studies when there is a potential impact to the seafloor. These surveys usually characterize the structure and/or spatiotemporal distribution of macrofaunal assemblages collected with sediment cores; however, many different sampling protocols have been used...

Functional phenotypes (e.g., subcortical surface representation), which commonly arise in imaging genetic studies, have been used to detect putative genes for complexly inherited neuropsychiatric and neurodegenerative disorders. However, existing statistical methods largely ignore the functional features (e.g., functional smoothness and correlation). The aim of this paper is to develop a functional genome-wide association analysis (FGWAS) framework to efficiently carry out whole-genome analyses of functional phenotypes...

Microwave and ultrasound have been demonstrated to be outstanding process intensification techniques for transesterification of oil. According to their mechanisms, simultaneous effects can surely bring about better enhancement than sole microwave or ultrasound. Therefore, this study aimed to investigate the important factors and their suitable levels in the KOH-catalyzed transesterification of soybean oil with methanol by using synergistic assistance of microwave-ultrasound (CAMU). The feasibility of application of CAMU in transesterification of oil was demonstrated...

We consider a basic quantum hybrid network model consisting of a number of nodes each holding a qubit, for which the aim is to drive the network to a consensus in the sense that all qubits reach a common state. Projective measurements are applied serving as control means, and the measurement results are exchanged among the nodes via classical communication channels. In this way the quantum-opeartion/classical-communication nature of hybrid quantum networks is captured, although coherent states and joint operations are not taken into consideration in order to facilitate a clear and explicit analysis...

Near-infrared spectroscopy (NIRS) is a convenient and safe brain-mapping tool. However, its inevitable confounding with hemodynamic responses outside the brain, especially in the frontotemporal head, has questioned its validity. Some researchers attempted to validate NIRS signals through concurrent measurements with functional magnetic resonance imaging (fMRI), but, counterintuitively, NIRS signals rarely correlate with local fMRI signals in NIRS channels, although both mapping techniques should measure the same hemoglobin concentration...

REVIEW
Meng Qiao, Tao Jiang, Shengxiang Ren, Caicun Zhou
The era of immune checkpoint inhibitors, especially programmed death-1 (PD-1)/programmed death ligand-1 (PD-L1) antibodies in the treatment of advanced non-small-cell lung cancer (NSCLC) is coming. Because of the lack of the definite biomarkers to select the optimal responders, only approximately 20% of patients with advanced NSCLC would respond to single checkpoint inhibitors-based immunotherapy. Moreover, primary or acquired resistance to conventional therapies is inevitable in most cases. Thus, combinations are pushed to move forward to be an alternative strategy and surely, it would be a future direction...

BACKGROUND: Guidelines summarize medical evidence, they identify the most efficient therapy under study conditions and recommend this therapy for use. The physician now has the challenge to translate a therapy that is efficient under laboratory conditions to a patient who is an individual person. To accomplish this task the physician has to make sure that (I) the ideal typical therapy is applicable and effective in this individual patient taking the special features into consideration, that (II) therapy is compliant with the norm including guidelines, laws and ethical requirements (conformity) and that (III) the therapy meets the patient's needs...

Stationary phase survival protein SurE from Salmonella typhimurium is a dimeric protein formed by the swapping of a tetramerization loop involved in the formation of a loose tetramer and a C-terminal helix. It functions as a phosphatase. The two-fold symmetry of the dimeric protein was lost in the mutants H234A and D230A/H234A in which a crucial hydrogen bond in the hinge involved in C-terminal helix swapping was eliminated. The catalytic activity of both mutants was drastically reduced. In contrast to the native protein, H234A exhibited positive cooperativity in its catalytic activity...

Biomechanical studies that involve normal, injured or stabilized human spines are sometimes difficult to perform on large samples due to limited access to cadaveric human spines and biological variability. Finite element models alleviate these limitations due to the possibility of reusing the same model, whereas cadaveric spines can be damaged during testing, or have their mechanicals behaviour modified by fatigue, permanent deformation or structural failure. Finite element models need to be validated with experimental data to make sure that they represent the complex mechanical and physiological behaviour of normal, injured and stabilized spinal segments...

OBJECTIVES: Despite of the European League Against Rheumatism (EULAR) provided different sets of recommendations for the management of cardiovascular risk in inflammatory arthritis patients, it must be pointed out that cardiometabolic comorbidity, such as type 2 diabetes (T2D), remains still underdiagnosed and undertreated in patients affected by rheumatoid arthritis (RA). METHODS: In this work, we designed a single centre, prospective study in order to better investigate the occurrence of T2D during the course of 1 year of follow-up...

In recent decades, complementary and alternative medicine (CAM) has become very popular in the treatment of several chronic diseases. Natural products as one of the CAM modalities offer potential opportunities to discover lead compounds for novel drug development. The use of CAM or natural products in the prevention of neurodegenerative diseases is comparatively a newer area. Natural therapeutics with anti-oxidative and anti-inflammatory salutations evidently plays a crucial role in protecting neurons. Of these, the most promising are caffeine, trigonelline, shogaol, curcumin, resveratrol, baicalein, wogonin, ginsenosides, tanshinones, withanolides, picrosides, parthenolide, cannabinoids, Devil's claw and white willow bark, including Chinese formulations Renshen Shouwu and Shengmai San...

Animal testing is still the most popular preclinical assesment model for liver fibrosis. To develop efficient anti-fibrotic therapies, robust and representative in vitro models are urgently needed. The most widely used in vitro fibrosis model is the culture-induced activation of primary rodent hepatic stellate cells. While these cultures have contributed greatly to the current understanding of hepatic stellate cell activation, they seem to be inadequate to cover the complexity of this regenerative response...

Enhancement of the systemic distribution of a chemical control agent by exploiting the normal movement of a solute through a plant's vascular system will surely increase its efficacy, and thereby allows for a reduction in both the volume and frequency of their application. Foliar uptake and phloem transport of N-[3-cyano-1-[2,6-dichloro-4-(trifluoromethyl)phenyl]-4-[(trifluoromethyl)sulfinyl]-1H-pyrazol-5-yl]-1-(β-D-glucopyranosyl)-1H-1,2,3-triazole-4-methanamine (GTF), a glucose-fipronil conjugate, involved a carrier-mediated mechanism in Ricinus communis by utilizing castor bean monosaccharide transporters...

INTRODUCTION: We report a case of a 57-year old man with a successful total endovascular treatment of a symptomatic penetrating arterial ulcer (PAU) of a lusorian artery together with a standard endovascular abdominal aortic aneurysm (AAA) repair. The lusorian artery is an aberrant subclavian artery and a congenital aortic arch anomaly with a reported prevalence of 0.4 to 2.6 %. Typical for the base of the lusorian artery is a Kommerell diverticulum making an endovascular approach even more difficult...

An "Upset stomach" is a common problem encountered by physicians involved in the care of children. It includes, diarrhea, vomiting or abdominal pain. Though often mild and self-limiting, at times there are uncommon life-threatening conditions that require urgent care. It is important for primary physicians to recognize "alarm signs" and make a referral to the specialist at the right time. At the same time it is important to recognize what is normal and re-assure the caregivers. A detailed history and a proper systemic examination are important at presentation, looking for any "red flags"...

Individual differences in attitudes to risk (a taste for risk, known probabilities) and ambiguity (a tolerance for uncertainty, unknown probabilities) differentially influence risky decision-making. However, it is not well understood whether risk and ambiguity are coded differently within individuals. Here, we tested whether individual differences in risk and ambiguity attitudes were reflected in distinct neural correlates during choice and outcome processing of risky and ambiguous gambles. To these ends, we developed a neuroimaging task in which participants ( N = 50) chose between a sure gain and a gamble, which was either risky or ambiguous, and presented decision outcomes (gains, no gains)...
